title: [Anesthetic management of a patient with Duchenne's muscular dystrophy undergoing radical repair for tetralogy of Fallot].
abstract: This report describes a 13-month-old-girl with Duchenne's muscular dystrophy (DMD) who had radical repair for tetralogy of Fallot safely. Patients with DMD are considered to be at risk of malignant hyperthermia (MH). Drugs for induction and maintenance were chosen from a list of agents rarely associated with MH. To wash out the inhalation anesthetics from the equipment, oxygen was circulated continuously for 24 hours. Dantrolene sodium was kept readily available in case of MH occurrence. Differential diagnosis during surgery is difficult in term of the episodes of MH and complications of cardiac surgery, as cardiac surgery is also associated with tachycardia, tachyarrhythmias, metabolic asidosis and red colored urine, which are frequently accompanied by MH. Although increased levels of CK, GOT, LDH and myoglobin strongly support the diagnosis of MH, such evidence can only be confirmed after operation. Fortunately, these factors recovered to the normal range without treatment by dantrolene sodium. During the cardiac surgery, treatment of MH may be delayed due to its late confirmation.
